Bug 415515

Application: plasma-discover (5.12.8)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.0.0-29-generic x86_64
Distribution: Zorin OS 15.1

-- Information about the crash:
- What I was doing when the application crashed:
- I was just trying to open Discover after updating threw "apt update && apt upgrade"
- Unusual behavior I noticed:
- There was no that error on older versions of KDE

The crash can be reproduced every time.

-- Backtrace:
Application: Центр программ Discover (plasma-discover), signal: Aborted
